Webthe entire FIFO. On the write side, the control (WR_EN) and data input (DIN) are sampled by the rising edge of WR_CLK and should be synchronous to the WR_CLK. For the read side the read control (RD_EN) should be synchronous to the RD_CLK and the output data (DOUT) is valid after the subse-quent rising edge of RD_CLK.

"WebJul 31, 2024 · The way the design works is by connecting the valid signal form my IP core to the fifo_wr_en of the ADC DMA. I havent used the sync part yet. The valid is asserted at the beginning of the frame and it stays high the whole duration of the frame. I tried with and without the ADC pack core. I would appreciate any suggestions? Many thanks.

WebOdds are that the FIFO will ignore the wr_en in this case. So it will probably behave as if its wr_en port was connected to @the_real_wr_en, which is defined as follows: assign the_real_wr_en = wr_en && !full; However some FPGA tools allow configuring the FIFO without this safety mechanism. If so, virtually anything can happen if an attempt is ... WebOct 15, 2024 · 1 Answer. rddata is an output port of the fifo_buff module. In the testbench, there is a wire named rddata which connects to the fifo instance. The problem is that the testbench then tries to drive the signal: That is illegal.
